CARE AND MAINTENANCE
CAUTION!
Cleaning the Air Filter

be reduced, leading to reduced performance, and increased

of the operating season, and about every two weeks during
periods of frequent operation.

Cleaning the Indoor Unit
Clean the indoor unit by wiping with a cloth dipped in
cool or warm water, then wipe with another soft, clean,
dry cloth.
CAUTION!
Never use water that is hotter than 40°C. The body
may warp or change colour.
Do not use inflammable sprays such as lacquer or
hair spray near the air conditioner.
The unit can be damaged by gasoline, benzine, thinners,
insecticides and other chemical agents.
When Not Using the Unit for Extended
Periods (One Month or More)
Operate the unit on fan mode for about one-half day on a
day with clear weather, to assure that the internal parts
are dry.
CAUTION!
When not using the unit for extended periods, discon-
nect the power plug for safety.
G When a plug is left connected, dust may collect on
the blades, leading to smoke and fire hazard.
Check the Power Cord
Check the power cord occasionally to confirm that it is
not damaged by cuts or abrasions. If you discover damage
to the cord, consult authorized service personnel.
Inspections and Repairs
Depending on the conditions of use, the internal parts
of an air conditioner will become dirty after about two
or three seasons of use, and performance may be af-
fected. For this reason, regular professional maintenance
is recommended. Consult authorized service personnel.
